    public abstract class HypericEnum

extends java.lang.Object
implements JSON, java.io.Serializable

Utility class for typesafe enums. People implementing such enums should subclass this class. Enums have a code and a description. The code must be unique for enums of a specific class. This has great use in things like Web-UI where you need a code representation as well as a string (rendering a listbox) Each enumeration also provides a resource bundle and locale property to look up the 'value' of the enumeration in that bundle. This class can also be used as a dynamic enumeration as long as all the enumerations use a unique code. XXX: It would be good to implement the PersistentEnum stylee via a UserType in Hibernate, so we don't have to do the conversion in every class that uses an enum. Don't have the time now.. :-( http://www.hibernate.org/203.html
